OT warning.
My N900 works as usual. Have not run into problems with CSSU updates. Although I'll have to admit that I am not constantly using it for anything else than phone calls and SMSes nowadays. Oh, and it is my default USB-"key".

Currently running 21.2011.38-1Tmaemo10-1, Flavor Testing
No kernel tweaks. Works great. Thank you for CSSU.
